Q: Can the swing check valve stand upright?: Swing check valve, vertical mount, horizontal loading can be.

Q: I installed here in the water pump inlet, water pump with a 100 tons of water tank, there are many pumps, long time running, the pump will heat the cylinder, there is no water in the cylinder, the pressure does not go. The water pump is imported. Is the check valve broken or is the installation position wrong?: Check valves are installed at the outlet of the pump. The reasons are as follows:The function of the check valve in the water supply system of the water pump is to prevent the impact of the high pressure water on the impeller of the pump. System in operation, for some reason, when the water pump suddenly stops running, the pressure inside the pump disappears, and the high-pressure water connected with the water pump outlet will reverse flow backwater pump. When the pump outlet is equipped with a check valve, it will be closed immediately to prevent the high pressure water reverse flow backwater pump. Prevent water pump reverse and so on.Check valve refers to rely on the flow of the media itself and automatically open and close the valve flap, used to prevent the media back flow valve, also known as check valve, Dan Xiangfa, counter flow valve and back pressure valve. The check valve belongs to an automatic valve, whose main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. The check valve can be mainly divided into swing check valve (rotating by gravity center) and lift check valve (moving along the axis). The function of this type of valve is to allow the medium to flow in one direction and to prevent flow in the opposite direction. Usually the valve is automatically work, fluid pressure flow in one direction, the valve open; the opposite direction of fluid flow by gravity, fluid pressure and valve closing effect on the valve seat, thereby cutting off flow.

Q: Check valve can not stop water, how to solve?: Valve is broken, change one, my family is like this

Q: What is the difference between the check valve rcvx and SFCV?: 3, swing type: liquid in the valve straight through, relying on the pressure to open the side of the rotating valve flap, after the loss of pressure, the valve depends on the weight back, the reverse of the liquid pressure closed valve. Other one-way valves (check valves), such as the sewage check valve, air defense explosion-proof valve and liquid use of the principle of the check valve is very similar.

Q: Is the check valve and relief valve something?: Not the same thing!!! Installed on the water heater will not have too much money, less than 10 should be enough, but most of the water heaters are non - targets, may not be too good to match, you'd better go to a larger plumbing market

Q: What are the types of check valves?: The check valve is divided into three kinds: lift check valve, swing check valve and butterfly check valve:1. lift check valve is divided into two types of vertical and horizontal.2. swing check valve is divided into single, double flap and multi flap type of three.3. butterfly check valve is straight through type.The above types of check valves can be classified into thread connection, flange connection, welding connection and clamp connection in connection forms of four kinds.Texture of material1. cast iron check valve2. brass check valve3. stainless steel check valve4. carbon steel check valve

Q: How many kinds of structure are there in the check valve?: 2. The swing check valve rotates around the shaft. Its fluid resistance is generally smaller than the lift check valve, it applies to larger caliber occasions. According to the number of valves can be divided into single swing type, double valve swing and multi valve swing type of three. Single swing check valves are generally applicable to medium calibre applications. Large diameter pipeline using single swing check valve, in order to reduce water hammer pressure, it is best to use water hammer to reduce the pressure of the slow closing check valve. Double check valves are suitable for large and medium diameter pipelines. Double check swing check valve with small structure and light weight is a kind of fast developing check valve. Multi valve check valve is suitable for large caliber pipeline;

Q: What is the difference between the check valve and the check valve?: 1, spring: the liquid from the bottom up, rely on the pressure spring controlled valve, the pressure disappears, the spring force the valve, sealing liquid backflow. Often used in the smaller diameter check valve.2, gravity: and spring similar to rely on the valve's own gravity closed to prevent backflow.3, swing type: liquid in the valve straight through, relying on the pressure to open the side of the rotating valve flap, after the loss of pressure, the valve depends on the weight back, the reverse of the liquid pressure closed valve. Other one-way valves (check valves), such as the sewage check valve, air defense explosion-proof valve and liquid use of the principle of the check valve is very similar.

Q: PPR check valve, butterfly valve, as well as water gauge which quota?: The valves and water meters installed in the same pipe are the same.

Q: What's the difference between the H76H model and the H76J check valve?: PN1.6-25mpa, 150LB-2500LB, 5K-63K class;6 check valve material: Q ductile iron, C steel, P-304, R-316, A, I titanium alloy chromium molybdenum steel;Check valve common model:Clip on lift check valves: H71X, H71H;Butterfly butterfly check valves: H76X, H76H;Pairs of wafer type check valves: H74H, H74I, H74M;Silent check valve: H42H, H42W;Micro resistance slow closing check valve: HH44H, HH46H, HH49H;Rubber disc check valves: HC44X;Muffler check valve: HC41H, HC41X, HC41T;Lift check valves: H41H, H41W;Swing check valves: H44H, H44W;Chute ball check valve: HQ41X;Welded check valves: H61Y, H62Y, H64Y.
